My Business is Not Successful

Hello, I came upon your site by chance. And I read a bit of your success stories. My situation is this. When I offer a service or products to people they hold on to my money and are usually unwilling to pay. They may promise to pay but most times they rarely do or they would delay for a long time. Also I put out a lot of information about my business hoping for patronage but it hardly ever comes. I struggle to earn money sometimes. Please assist me. I would greatly appreciate it.

Thank you and regards
